ln these drawings we have illustrated one embodiment of our inventionand have shown the same as applied to a confection forming and wrappingmachine. This machine comprises a support adapted to receive a batch ofcandy in a plastic condition and deliver the same to suitable reducingand feeding mechanism which draws the candy into a bar of suitable anduniform diameter and feeds this bar to a cutting device which dividesthe same into small portions or confections. formed are delivered to acarrier which, in turn, delivers them to the wrapping mechanism. sDuring the passage from the cutting device to the wrapping mechanism theconfections are tempered and are reduced to a uniform size. After beingdischarged from the carrier the confections, with their wrappers, aredelivered to a conveyer which presents them in succession to folding-and twisting devices which complete the wrapping ofthe confection andthen discharge the completely wrapped confection from the machine.

The several mechanisms comprising the machine may, of course, bearranged and supported in any suitable manner. In the present instancewe have shown the several mechanisms as mounted fupon a main frame 1comprising a flat top or supporting surface 2 and mounted upon verticalstandards or legs 3. Extending transversely to the main frame near t erear end thereof and below the top thereo is a main driving shaft 4which is journaled in the side members of the main frame and extends forsome distance on the opposite sides of that frame.-

A suitable driving wheel, such as a belt wheel 5, is loosely mounted onthat portion of the shaft 4 which projects beyond one side of the mainframe and is adapted to be connected to and disconnected from `a shaft@5 by suitable clutch mechanim under the con- The confections thus.

incarica trol of the operator. This mechanism is` here shown ascomprising a friction drum 6 rigidly secured to the driving wheel andadapted to coperate with friction shoes 7 carried by levers 8 pivotallymounted upon lugs 9 carried by a sleeve 10. This sleeve is rigidlysecured to the shaft 4 and the ends of the levers 8 onthat side of thesleeve `opposite the driving wheel 5 extend some distance beyond the'endof the sleeve and are adapted to be'actuated by a cone 11 slidablymounted on the shaft 4. The ends of the levers are preferably providedwith adjustable stops 12 arranged to engage the cone 11 and regulate theamount of pressure exerted on the shoes 7. The cone may be actuated inany suitable manner, but, as here shown, is provided with the usualgrooved collar 13 into which extend pins 14; carried by the arms of ayoke 15. This yoke is pivotally mounted upon a bracket 16 rigidlysecured to one side of the main frame 1 and-has rigidly secured theretoan arm 17 which extends transversely to the main frame and is providedon the opposite side thereof with a handle 18, by means of which the arm17, yoke 15 and cone 11 may be actuated. From this main driving shaft 4all of the mechanism comprising the machine are actuated.

The support for' the batch of candy and the reducing and feedingmechanism are here shown as supported on a bracket 19 rigidly secured toone side of the main frame, in the present instance that side oppositethe side on which the driving wheel is mounted, and at a point near therear end thereof. Tt will be understood that in this description thedirection in which the confections move in their passage through themachine is considered the forward direction,

and,l consequently, the front end of the ma.

chine is the end at which the wrapped candy is discharged and the rearend is'the nd at which the batch is supported. The support employed inthe present machine also constitutes a diminisher which so shapes thelower end of the batch as to enable itito be acted upon by the reducingand feeding rollers. This support or diminisher comprisesa cone-shapedreceptacle arranged in a substantially vertical position and open atboth its upper and its lower ends. The walls of the receptacle are madeup of a series of tapered sections or staves 20 which are so supportedas to be movable toward and away from a vertical line extendingcentrally to the receptacle and also to have a vertical movement, thecombined movements serving to compress the batch of candy into acone-shape and to draw the same downmeans oft's'trips of resilientmaterial. 4, In thepres'ent instance we have employed strips of softrubber, as indicated at 21." These strips are'providedwith thickenedcentral portions 22 extending beyond the opposite sides of the body ofthe strip and adapted to enter recesses 23 formed in the edges of thesections of the diminisher. rlhe movement of the sections relativ@ oneto the other is slight and the-resiliency ofthe soft rubber enables thesame to be contracted and to expand with the movements of the'sections,thereby keeping the spaces between the sections closed and preventingthe candy from entering the same. A hopper-20 is rigidly supported abovethe diminisher and a gasket b of rubber or other resilient material isinterposed between the upper ends of the sections 2O and the hopper topermit of the 20 vertical movement of the sectionsland prevent thematerialescaping between the hopper and diminisher. Similar gaskets areplaced between the lower ends ofthe secf tions andthe supporting member.

-The desired movements may be imparted to the several sections 20 of thediminisher in any suitable mannerand we' have here shown one method ofimparting these movements to the sections which we have foundsatisfactory. Each section has pivotally connected thereto near itsupper and lower ends links 24 and 25, respectively.v The \links 25,which are connected at one end to the sections 2O near their lower ends,are connected at their opposite ends to pivot lugs 26 carried by andpreferably formed integral with an annular supporting member 27. Thissupporting member is mounted on a plate 28 carried by two side members29 of a bracket30, which, in turn, is mounted upon the bracket 19 andwhich serves as a support both for the diminisher and for the reducingand feeding devices. The links 24 which are connected to the upper endsoflthe sections 20 are pivotally connected at their outer ends to anannular support 31 which extends about the diminisher and which isconnected to the lower annular support 27 by means of rods 32. p

Vertical movement' is imparted to the sections of the diminisher bymeans of a ring Y 33 extending about` the lower end of the diminisherimmediately labove the inner ends of the lower series of links 25. Astop 34 is rigidly secured to each section of the diminisher immediatelyabove the ring 33 and these stops, together with the inner ends ofthelinks 25 and the lugs-to which.

these links are pivoted, serve to limit the l vertical movement of thering. /Tlis ring is actuated by means of a lever 34 pivotallyl connectedat one end to a fixed part of the machine. In the present instance thisconnection is made bymeans Acfa link 35 pivotally connected at one endto the adjacent Ltrunnions 39 rigidly secured to the opposite v.downwardthe lower end of the batch of candy. The upward and outward' move-,which is rigidlysecuredto the plate 28 of thefbracket 30. The lever 34is provided vwith an annular portion, as indicated at 37, wlnch extendsloosely about the diminisher just above thev ring 33 and is connected tothat ring by means of bearing lugs 38 depending therefrom and arrangedtoreceive sides of the ring 33. The movable end of the lever 34 isconnected by means of a pitman 40 with a crank pin 41 carried by a gear42 mounted on the bracket 19 and meshing with a second gear 43 mountedon the driving shaft 4. It will be apparent that the movement of thelever 34 will raise and lower thering 33, and as the movement or thering relative to the sections of the diminisher is limited, as abovedescribed, the movement of the ring will cause a corresponding movementof the sections 20 of the diminisher. The .vertical movement of thesectionscauses the links 24 and 25 to be moved about their pivotalconnections to the fixed supports, and, consequently, the sections aremovedI inward or outward a distance corresponding to the movement of thelinks about their pivotal centers. In this manner there is successivelyimparted to the sections an inward and downward movement and an upwardand outward movement. The inward and downward movements serve tocompress and draw ments of the sections increase the diameterl of thediminisher and permit the batch of candy to drop downward In this lowerposition it is again engaged by the sections as they again move inwardand downward.

The supporting plate 28 of the bracket 30 has an opening formed thereinimmediately beneath Ithe opening in the annular support 27 and supportedfrom the bracket beneath this opening are two feeding and reducingrollers 44 and 45. These rollers are of a known construction and each isprovidedin its periphery with a groove and the two rollers are arrangedwith their axes in substantially the same horizontal plane and withtheir peripheries in engagement,4 and, consequently, a vertical passageis formed between the rollers. The arrangement of the rollers `is suchas to bring this passage directly beneath the opening in the lower endof the diminisher. The rollers may, if desired, beprovided with pins 46arranged within the grooves to increase the gripping action 'of therollers and vfacilitate the feeding of the candy and the drawing of thesame from Vthe batch. These rollers are here shown as mounted uponshafts 47 and 48. journaled in the side members 29 of the bracket 30,which bracket extends 13e .shafts on one side of the bracket and in thismanner are supported vin a position in which they are readilyaccessible. The shaft 47 has mounted thereon between the two sidemembers of the frame a worm wheel 49 which meshes with a worm 50 mountedon a vertical shaft 51, which, in turn, is mounted in bearings carriedby the bracket 19 and has 'at its lower end a bevel pinion 52 whichmeshes with a bevel gear 53 mounted on the driving' shaft 4. The shafts47 and 48 have mounted on those ends opposite the ends on which therollers are mounted intermeshing gears 54 and 55, by means of whichmovement is imparted from the shaft 47 to the shaft 48 and the tworollers 44 and 45 are caused to rotate in opposite directions. it passesbetweenthe rollers 44 and 45 engages a curved guide or chute 56 and isguided thereby to-a second pair of feeding and reducing rollers 57 and58. These rollers are similar in construction to the rollers 44 and 45,but are somewhat smaller 'and have theiraxes arranged in a verticalplane so as topresent a substantially horizontal opening for the passageof the bar of candy. IThey are preferably driven from the gear 55 whichrotates the shaft 48 of the roller 45, this being accomplished by meansof an intermediate pinion 59 meshing with the gear 55. and with a gearA60 mountedon a shaft 61 'of the upper roller 57. A second gear 62, alsomounted on the shaft 61, meshes with a gear 63 mounted on a shaft 64 ofthe lower roller, thereby rotating these rollers in opposite directions.The bar of .candy passes from the second pair of reducing and 'feedingrollers 57 to the third and final pair of rollers. These rollers, whichare indicatedat 65 and 66, have their axes arranged in a substantiallyhorizontal plane so that the bar is discharged therefrom in asubstantially vertical plane. The space between the second and thirdpair of rollers is bridged by a chute 67 and a suitable guard 68 ismounted upon the side members ofthe frame, extends above the path of thebar of candy and serves to direct the same downward betweenthe tworollers 65 and 66. This third pair of rollers are actuatedintermittently so as to feed the bar of candy forward equal distances atfixed intervals. This intermittent movement of the rollers may beaccomplished in any suitable manner, but we have here shown a pawl andratchet mechanism for imparting this movement to the roller 65. Thismechanism comprises a ratchet wheel 69l vmounted on a shaft 70 of theroller 65.

A pawl 71 has one end arranged to engage The bar of candyl asv memos theteeth of the ratchet 69 and is pivotally connected at its other end tothe adjacent end of a reciprocating rod 72 which is slidably mounted insuitable bearings supported by the side members 29 of the frame 30 andhas between its ends a projection 73 arranged in the path of a cam 74mounted on the upper end of a vertical shaft 75 journaled in bearings inthe brackets 19 and having at its lower end a bevel pinion 7 6 meshingwith a corresponding pinion 77 on the drive shaft 4. Thus, at eachrevolution of the shaft 75 the rod 72 and pawl 71 will be moved forwardand the ratchet wheel and the roller 65, with which it is connected,rotated through the space of one tooth. A spring 78 is coiled about therod 72 and is confined between one of the bear ings for the rod and acollar 79 rigidly secured to the rod and serves tol retract the rodafter each forward movement thereof. A movement corresponding to themovement of the roller 65 is imparted to the roller 66 by means of agear 80 mounted on the shaft of the roller 65 and meshing with a similargear 81 mounted on a shaft 82 of the roller 66. Those portions of theside members 29 of the frame 30, in which the Ishafts (0 and 82 of therollers 65 yand 66, respectively, are journaled, are pivotally connectedto Athe main portions of the side members of that frame, as shown at 83,thereby enabling the end of the frame and the rollers 65 and 66 to bemoved into a substantially vertical position to permit access to theparts arranged within the same and to be herein described. A tube orchute 84 is preferably provided to form a guide for the bar of candy asit leaves the last pair of rollers 65 and 66.

A suitable cutting device is arranged to act upon the bar of candy as itleaves the feeding and reducing rollers and to divide This cuttingdevice is here shown as a rotary diskcutter 85 connected with and.arranged eccentrically to the upper end of`a vertical shaft 86journaledin a bearing 87 mounted on the top 2 of the main frame 1 andhaving at its lower end a bevel pinion 88 meshing with a correspondingpinion 89 on the driving shaft 4. Mounted on the upper end of thebearing 87 and preferably formed integral therewith isa .housing 90substantially cylindrical in shape and having its upper vend open.Mounted within the housing 90 and rigidly secured to the upper end ofthe shaft 86 isa cylindrical block 91 having formed therein an annulargroove 92. The block 91 also has a vertical bearing 93'in which isjournaled. a shaft 94 carrying the cutter 85. Rigidly secured to theshaft 94 at a point adjacent the groove 92'is a pinion 95 which mesheswith a rack 96` carried by 'theinner wall of the cylindrical housing 99and `fixed against movement relative thereto. v

ment when engaged by the cutter and enable's a clean, smooth cut to bemade.

The confections which are severed from the bar are received by a carrierwhich conveys the same to the point at which they are delivered to thewrapping mechanism. This carrier, as here shown, comprises an annularframe 97 having a series of pockets 98 open at the upper and lower endsand of a size corresponding approximately to the size of the confection.In the present instance this annular frame. 97 is secured to the outerends of a series of radial spokes or arms 99 whichv connect the same, toa hub 100 which is ro. tatably mounted on a vertical shaft 101 fixed ina socket 102 carried by a bracket 103 secured to the top 2 of the mainframe 1. The spaces between the arms or spokmes 99 may, if desired, beclosed to prevent the passage of chips or particles of candy which mayfly from the cutter. lAn annular plate 104 is arranged beneath theseries of pockets 98 and forms the bottoms of these pockets. This plateis rigidly secured to a fixed part ofthe machine and has no movementrelative thereto. In the present machine we have shown the plate ascarried by a series of arms 105 which are rigidly secured to the socket102. It will be noted that the plate or ring 104 is 'spaced a shortdistance away from the lower edge of the pockets 98, thus increasing thedepth of the pockets. The carrier is so arranged relative to thedischarge tube 84 of the feeding and reducing rollers that the severalpockets will pass successively beneath this tube and each will receive aconfection. The carrier is actuated intermittently and its movements areso timed that they will take place during the interval between themovements of'the intermivttentlyfmovable feeding rollers. Thisintermittent movement of the carrier may be secured infany suitablemanner. In the present instance we have r'provided the carrier with anannular rack 106 which is here shown as arranged immediately beneath theannular frame 97 and in substantially the same horizontall plane withthe arms or spokesg9. Y The annular frame 97 is mounted on or connectedto the upper edges of the s okes so as to elevate the ockets 98 above te level of the spokes of t e carrier. The

teeth of this rack are preferably spaced seine distance apart and thoseportions of the rack lying between the teeth project outward a distancealmost equal to the length of the teeth and have their outer edgesconcave. A one tooth gear 107 is arranged near the rack to actuate thesame. This gear is preferabl mounted upon the upper end of a shaft 10rotatably mounted in a bearing 109 mountedl on the top of the main frameand has at its lower end a bevel gear 110 meshing with a correspondinggear 111 secured tothe drivino' shaft 4. The body of the gear 107 issubstantially cylindrical and is adapted to engage the concave edges ofthose portions of the .rack lying between the teeth and rack to hold therack against movement during the rotation of the gear, therebypreventing any displacement Aof the pockets 98 relative to the dischargetube 84. The annular frame 97 is so arranged that the upper ends of the'pockets 98 are in a plane Aslightly lower than the discharge tube 84,the space be' tween the two parts being just sufficient to permit thepassage of the cutter 85. Consequently, the end of the bar of candywhich is to form the confection will be fed into the pocket before it issevered from the body portion of the bar. By spacing the annular plate,which forms the bottoms of the pockets, away from the lower edge oftheframe, the depth of the pockets is increased and the length oftheconfection when 1t is severed from the bar is slightly greater than thedepth of the pocket proper. f,

The confection'when severed from the bar of candy is in a more or lesswarm and soft condition, and, during' the interval consumed by themovement ofthe confectlons from the point where they are received by thecarrier to. the point where they are discharged, the

confections will cool and shrink, the amounty a batch willbe quite warmand soft and the shrinkage will be correspondingly great, but thoseformed from the latter part of the batch will be much cooler, and,consequently, the shrinkage will be correspondingly less. The lengths ofthe several confections when they are severed from v'the bar are thesame. Therefore, the dilference in shrinkage leaves the confections ofdifferent lengths, and, in order that the confecf tions when wrapped maybe ofl a uniform length, we have provided means for sizing eachconfection before it is discharged from the carrier. To this end we havearranged aninclined plate or strip 112 on that portion of the annular.plate 104 -immediately preceding the pointfof discharge of theconfections from the carrier. `The rear edge of this strip, where theconfection first comes
